Abstract
The adaptive immune system is composed of [alpha beta] T cells, [gamma delta] T cells, and B cells, all of which express diverse rearranged antigen receptors and have been conserved together through evolution. [gamma delta] T cells make up the minority of circulating T cells and perform many of the same effector functions as [alpha beta] T cells, including cytotoxic functions and the production of cytokines like IL-17, IFN-[gamma], and IL-4. However, the conservation of [gamma delta] T cells suggests that they fill a non-redundant role in the adaptive immune system. Because their functions overlap, it is likely that [gamma delta] T cells are distinctive from [alpha beta] T cells in the way they are triggered by antigen. These antigenic triggers of [gamma delta] T cells remain poorly defined, but a more thorough knowledge of this repertoire will enhance understanding of the role of [gamma delta] T cells in the immune response. The identification of new [gamma delta] T cell antigens was undertaken, resulting in the discovery of hapten small molecule [gamma delta] T cell ligands and the identification of a diverse group of additional candidate [gamma delta] T cell ligands. With the discovery that [gamma delta] T cell receptors can recognize small molecules in addition to their known large protein ligands, it is clear that [gamma delta] T cells fill a unique role in the adaptive immune system is solidified with a broad capacity for antigen recognition along with all the functionality of T cells, and are uniquely situated to function together with [alpha beta] T cells and B cells in a concerted antigen-specific response.
